The <a href="http://www.unece.org/cefact/ebxml/CCTS_V2-01_Final.pdf">ebXML Core Components Technical Specification</a> (<a href="http://isotc.iso.org/livelink/livelink?func=ll&amp;objId=3233203&amp;objAction=browse&amp;sort=name">ISO 15000-5</a>)&nbsp; presents a methodology for developing a common set of semantic building blocks to represent the general types of business data in use today. It also provides for the creation of new business vocabularies and restructuring of existing business vocabularies. ebXML CCTS is advanced by the <font size="2"><a href="http://www.untmg.org/index.php?option=com_content&amp;task=view&amp;id=12&amp;Itemid=113">Techniques and Methodologies Group (TMG)</a> of the</font> <a href="http://www.unece.org/cefact/">United Nations Centre for Trade Facilitation and Electronic Business (UN/CEFACT)</a>.<br /><br />The Core Components Technical Specification describes and specifies a new approach to the well-understood problem of the lack of information interoperability between applications in the e-business arena. Traditionally, standards for the exchange of business data have been focused on static message definitions that have not enabled a sufficient degree of interoperability or flexibility. CCTS addresses the need for a more flexible and interoperable way of standardising Business Semantics.
